Perleidus is an extinct genus of ray-finned fish from the Triassic period. Fossils have been found in the Middle Triassic of Italy, Switzerland, and China. The inclusion of Early Triassic species in the genus Perleidus was questioned.
Pholidophorus is an extinct genus of stem-teleost fish. Numerous species were assigned to this genus in the past, but only the type species Pholidophorus latiusculus, from the Late Triassic of Europe, is considered to be a valid member of the genus today.
Thoracopterus is an extinct genus of overwater gliding ray-finned fish. It was common to the late Middle Triassic and Late Triassic epochs in what is now Europe and China.
Pteronisculus is an extinct genus of prehistoric bony fish that lived during the Early Triassic and Middle Triassic epochs of the Triassic period. The preoccupied genus name "Glaucolepis" Stensiö, 1921 is a synonym of Pteronisculus White, 1933.
Eosaurichthys is an extinct saurichthyid ray-finned fish that lived during the late Permian epoch in what is now China. It closely resembles its daughter genus, Saurichthys, in both form and morphology.
Gigantopterus is an extinct genus of prehistoric bony fish that lived during the Carnian stage of the Late Triassic epoch.
Allolepidotus is an extinct genus of prehistoric neopterygian ray-finned fish from the Middle Triassic epoch. It is referred to the halecomorph order Panxianichthyiformes.
Boreosomus is an extinct genus of Triassic ray-finned fish. It was first described from the Arctic island of Spitsbergen, but was later also discovered in other parts of the world. Boreosomus had a worldwide distribution during the Early Triassic. Fossils of Boreosomus were found, apart from Spitsbergen, in Greenland, Madagascar and Canada. The type species is Boreosomus arcticus.
Hemicalypterus is an extinct genus of prehistoric ray-finned fish that lived during the late Triassic period. It contains a single species, Hemicalypterus weiri. Fossils have been collected in the southwestern United States, including Utah and New Mexico. Hemicalypterus belonged to the family Dapediidae, and like other members of its family, it was a deep-bodied fish with a covering of thick ganoid scales. It differed from other dapediids in lacking scales on the posterior part of the body, and in possessing unusual, multicuspid teeth. These teeth were similar to those of modern-day herbivorous fish, which indicates that Hemicalypterus may have been a herbivore as well.
Prohalecites is an extinct genus of ray-finned fish from the Ladinian and possibly Carnian (Triassic) of Italy. It is the oldest known teleosteomorph, a group that includes extant teleosts and their close fossil relatives.
Saurorhynchus is an extinct genus of carnivorous bony fish. It is the youngest representative of the family Saurichthyidae and the order Saurichthyiformes. This family is known for its large, elongate jaws, similar to modern Belonidae. Saurichthyidae also includes the Permian genus Eosaurichthys and the Triassic genus Saurichthys.
Pholidorhynchodon is an extinct genus of ray-finned fish that lived in the Triassic. Its fossils have been found in Italy, in the Zorzino Limestone Formation in Cene.
Sinosaurichthys is an extinct genus of saurichthyid ray-finned fish, which existed in southwestern China during the Middle Triassic. Fossils have been found in the Upper Member of the Guanling Formation of two localities: Yangjuan of Panxian County, Guizhou Province, and Dawazi of Luoping, Yunnan Province, China.
Saurichthyiformes is an extinct order of ray-finned fish which existed in Asia, Africa, Australia, Europe and North America, during the late Permian to early Middle Jurassic. Saurichthyiiformes comprise two families, Saurichthyidae and Yelangichthyidae. Whereas Yelangichthyidae is monotypic, Saurichthyidae includes at least two genera, Saurorhynchus and the very speciose Saurichthys. Additionally, the subgenera Costasaurichthys, Eosaurichthys, Lepidosaurichthys, and Sinosaurichthys are frequently used to group species. Saurichthyiforms were highly successful predators, and with Yelangichthys possibly even included durophagous forms. Species are known from both marine end freshwater deposits. They had their highest diversity during the Early and Middle Triassic.
Archaeomaenidae is an extinct family of stem-teleost fish found in freshwater environments of Jurassic New South Wales of Australia, China, and Antarctica, and in Lower Cretaceous New South Wales and Mongolia.
Candelarialepis is an extinct genus of prehistoric ray-finned fish that lived during the Induan age of the Early Triassic epoch in what is now Nevada. It was described from the Candelaria Formation.
Ardoreosomus is an extinct genus of ray-finned fish. It was described from the Induan aged Candelaria Formation of Nevada, United States, which was located near the equator during the Early Triassic epoch. It contains only one species, A. occidentalis (monotypy).
Ginglymodi is a clade of ray-finned fish containing modern-day gars (Lepisosteidae) and their extinct relatives, including the family Lepidotidae and the orders Semionotiformes and Kyphosichthyiformes, and various other extinct taxa. Ginglymodi is one of the two major subgroups of the infraclass Holostei, the other one being Halecomorphi, which contains the bowfin and its fossil relatives.
Teffichthys is an extinct genus of ray-finned fish from the Early Triassic epoch. Fossils have been found in Madagascar, and possibly also in Angola, Canada, Greenland, and Svalbard.
Pholidophoridae is an extinct family of primitive stem-teleost fish that lived during the Triassic period. Most of the genera are from the Late Triassic of Europe, but one (Malingichthys) is known from the Middle Triassic (Ladinian) of China. The pholidophorids were historically united with several other stem-teleost lineages into the order Pholidophoriformes; however, Pholidophoriformes in its traditional sense is now thought to be paraphyletic with respect to crown group teleosts.
